为连接字符串属性指定的值无效

Question

import pyodbc as po    

connection_string = """
driver=ODBC Driver 17 for SQL Server;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=True;
"""

connection = po.connect(connection_string)

输出：

服务器名称正确。
数据库名称正确
存在 ODBC 驱动程序。
Windows SSMS 中的身份验证有效。

Answer 1

根据this microsoft documentation，可识别的值为true、false、yes、no和sspi

pyodbc documentation 说，您可以通过提供 Trusted_Connection 属性来使用您的 Windows 帐户而不是 username/password 进行身份验证：Trusted_Connection=yes

所以它看起来是 connectionstrings sql server main page shows you the connection string for .Net libraries. If you click on any of the pages for a specific version of the driver under "ODBC drivers" (like 17 or 13 or 11)，它显示 Trusted_Connection=yes

Answer 2

For [ODBC Driver 17 for SQL Server] driver
It should be like 
connection_string = "
driver=ODBC Driver 17 for SQL Server;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=yes;
"""

For [SQL SERVER DRIVER]
It should be like :

connection_string = "
driver=SQL SERVER DRIVER;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=True;
"
